Guys I almost lost my patience with my RB S5 yesterday. It was running way too lean with a fast uncontrollable idle. But anyway I think my front bearing is trash. I can't see any wet oil because of the dusty track condition, but I do see caked up dirt around the fly wheel. So my question is...could it be a leaky bearing or is dirt going to cake up around this area anyway? Guys I would really appreciate your input.
